Title: Replace `joinedload` with `subqueryload` for join tables

* Using `joinedload` for multiple join tables on objects with many
mappings can cause extremely large query results, which slows
responses to a crawl. There's likely a happy medium to be found
through analytics, but for now let's be conservative to avoid the
run-away cases.
